Picosecond Avalanche Detector — working principle and gain measurement with a proof-of-concept prototype
/ Paolozzi, L. (Geneva U. ; CERN) ; Munker, M. (Geneva U.) ; Cardella, R. (Geneva U.) ; Milanesio, M. (Geneva U.) ; Gurimskaya, Y. (Geneva U.) ; Martinelli, F. (Geneva U.) ; Picardi, A. (Geneva U. ; CERN) ; Rücker, H. (IHP, Frankfurt) ; Trusch, A. (IHP, Frankfurt) ; Valerio, P. (Geneva U.) et al.
The Picosecond Avalanche Detector is a multi-junction silicon pixel detector based on a $\mathrm{(NP)_{drift}(NP)_{gain}}$ structure, devised to enable charged-particle tracking with high spatial resolution and picosecond time-stamp capability. It uses a continuous junction deep inside the sensor volume to amplify the primary charge produced by ionizing radiation in a thin absorption layer. [...]

Defect characterization studies on neutron irradiated boron-doped silicon pad diodes and Low Gain Avalanche Detectors
/ Himmerlich, Anja (CERN) ; Castello-Mor, Nuria (CERN) ; Rivera, Esteban Curras (CERN) ; Gurimskaya, Yana (CERN) ; Maulerova-Subert, Vendula (CERN ; Hamburg U.) ; Moll, Michael (CERN) ; Pintilie, Ioana (Bucharest U.) ; Fretwurst, Eckhart (Hamburg U.) ; Liao, Chuan (Hamburg U.) ; Schwandt, Jorn (Hamburg U.)
High-energy physics detectors, like Low Gain Avalanche Detectors (LGADs) that will be used as fast timing detectors in the High Luminosity LHC experiments, have to exhibit a significant radiation tolerance. Thereby the impact of radiation on the highly boron-doped gain layer that enables the internal charge multiplication, is of special interest, since due to the so-called Acceptor Removal Effect (ARE) a radiation-induced deactivation of active boron dopants takes place. [...]

The proof-of-concept prototype of the Picosecond Avalanche Detector, a multi-PN junction monolithic silicon detector with continuous gain layer deep in the sensor depleted region, was tested with a beam of 180 GeV pions at the CERN SPS. The prototype features low noise and fast SiGe BiCMOS frontend electronics and hexagonal pixels with 100 μm pitch. [...]

The Boron–Oxygen (BᵢOᵢ) Defect Complex Induced by Irradiation With 23 GeV Protons in p-Type Epitaxial Silicon Diodes
/ Liao, C (Hamburg U.) ; Fretwurst, E (Hamburg U.) ; Garutti, E (Hamburg U.) ; Schwandt, J (Hamburg U.) ; Moll, M (CERN) ; Himmerlich, A (CERN) ; Gurimskaya, Y (Geneva U.) ; Pintilie, I (Bucharest, Nat. Inst. Mat. Sci.) ; Nitescu, A (Bucharest, Nat. Inst. Mat. Sci.) ; Li, Z (Ludong U., Yantai ; Zaozhuang U.) et al.
In this work, the thermally stimulated current (TSC) technique has been used to investigate the properties of the radiation-induced interstitial boron and interstitial oxygen defect complex by 23-GeV (
$E_{\text {kin}}$
) protons, including activation energy, defect concentration, as well as the annealing behavior. At first isothermal annealing (at 80 °C for 0–180 min) followed by isochronal annealing (for 15 min between 100 °C and 190 °C in steps of 10 °C), studies had been performed in order to get information about the thermal stability of the interstitial boron and interstitial oxygen defect in 50-
$\Omega $
cm material after irradiation with 23-GeV protons to a fluence of
$6.91\times 10^{13}\,\,{\text {p/cm}^{2}}$

Radiation damage in p-type EPI silicon pad diodes irradiated with protons and neutrons
/ Gurimskaya, Yana (CERN) ; Dias De Almeida, Pedro (CERN ; Cantabria U., Santander) ; Fernandez Garcia, Marcos (Cantabria U., Santander) ; Mateu Suau, Isidre (CERN) ; Moll, Michael (CERN) ; Fretwurst, Eckhart (Hamburg U.) ; Makarenko, Leonid (Belarus State U.) ; Pintilie, Ioana (Bucharest, Nat. Inst. Mat. Sci.)
In view of the HL-LHC upgrade, radiation-tolerant silicon sensors containing low-resistivity p-type implants or substrates, like LGAD or HV-CMOS devices, are being developed in the framework of ATLAS, CMS, RD50 and other sensor R&D; projects. These devices are facing a particular problem — the apparent deactivation of the doping due to the irradiation, the so-called acceptor removal effect. [...]
